What does it mean when probability is independent?

Mathematics
1 answer:
g100num [7]2 years ago

When an event is independent of the other, it means Event A does not influence Event B. 

For example, if one was to find the probability of someone owning a car and what there neighbour eats, there is no correlation. In this situation, the events are independent. 

Hope I helped :)

Line segment XY is a directed line segment beginning at point X(9, 2) and ending at point Y(-6, 2). Find the point Z on the line
lozanna [386]

Answer:

(-\frac{3}{8},2)

Step-by-step explanation:

Point Z divides XY into a 5:3 ratio, so Z is 5/3 of the way from X to Y.  That ratio is k, found by writing the numerator of the ratio (5) over the sum of the numerator and the denominator (5 + 3 = 8).  Our k value is 5/8.  Now we will find the rise and run values which is the slope of this line segment:

m=\frac{2-2}{-6-9} =\frac{0}{-15}

Coordinates are found in this formula:

Z(x,y)=(x_{1}+k(run),y_{1} +k(rise))

Filling that in:

Z(x,y)=(9+\frac{5}{8}(-15),2+\frac{5}{8}(0))

which simplifies to

Z(x,y)=(9-\frac{75}{8},2+0)

which gives us the final coordinates of Z to be Z(x,y)=(-\frac{3}{8},2)

When exercising, the maximum heart rate (r ) in beats per minute is modeled by the equation shown in the box, where (a ) represe
worty [1.4K]

Answer:

186 beats per minute

Step-by-step explanation:

The maximum heart rate (r ) in beats per minute is modeled by the equation :

r = 220 - a ...(1)

Where

a is age of the person in years

If Sanchez age is, a = 34 years

Put a = 34 in equation (1)

r = 220 - 34

= 186 beats per minute

Hence, the maximum heart rate is 186 beats per minute.

maxonik [38]

The equation will be like this,

6.89 + t = 8.00

t = 8 - 6.89

t = 1.11

tips = $1.11

6.89 + t = 8.00

To sum up the total amount of cash and coins you have, first, sort each invoice and coin by denomination. Create a separate stack for each denomination and count how many denominations or coins you have.

For each denomination of banknotes and coins, multiply the number you have by the denomination. For example, if you have 4 out of $ 10, multiply by 4x10 to get $ 40. If you have three $ 5 bills, multiply by 3x5 to get $ 15.

Sum the totals to calculate the total amount.
